1. X Amp Reamp Track Reamp Track The advantages of recording a track this way are many Once the original track has been recorded the engineer and producer can try different amplifiers and sounds without tiring out the player with relentless repetition For the player engineer the track can be recorded then the player can then sit in the control room and listen to a variety of guitar effects or amplifiers before committing a final sound to the track The X Amp can also be used on other instruments Keyboard tracks can be given extra life by warming up their sound by sometimes driving them through distortion pedals or tube guitar amps Vocal tracks can also be twisted into new sounds by introducing these fun effects Radial Engineering Ltd 1 X AMP Reamper Radial FEATURE SET INPUT PANEL 1 LINE LEVEL XLR INPUT The input to the Radial X Amp is a balanced line level female XLR This is typically fed from the output of a recording device or mixing console The XLR connector is wired with pin 2 hot following the AES standard 2 GROUND A ground lift switch disconnects pin 1 ground at the XLR input Depressing this switch assumes you will be providing a ground path via the OUT 1 to your amplifier Lifting the ground often helps reduce hum or buzz caused by so called ground loops 3 CABLE CLAMP Used to secure the power supply cable and prevent accidental power disconnection 4 POWER The 15VDC power supply is connected h2. is no longer available Radial reserves the right to replace the product with a similar product of equal or greater value In the unlikely event that a defect is uncovered please call 604 942 1001 or email service radialeng com to obtain a RA number Return Authorization number before the 3 year warranty period expires The product must be returned prepaid in the original shipping container or equivalent to Radial or to an authorized Radial repair center and you must as sume the risk of loss or damage A copy of the original invoice showing date of purchase and the dealer name must accompany any request for work to be performed under this limited and transferable warranty This warranty shall not apply if the product has been damaged due to abuse misuse misapplication accident or as a result of service or modification by any other than an authorized Radial repair center THERE ARE NO EXPRESSED WARRANTIES OTHER THAN THOSE ON THE FACE HERE OF AND DESCRIBED ABOVE NO WARRANTIES WHETHER EXPRESSED OR IMPLIED INCLUDING BUT NOT LIMITED TO ANY IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE SHALL EXTEND BEYOND THE RESPEC TIVE WARRANTY PERIOD DESCRIBED ABOVE OF THREE YEARS RADIAL SHALL NOT BE RESPONSIBLE OR LIABLE FOR ANY SPECIAL INCIDENTAL OR CONSEQUENTIAL DAMAGES OR LOSS ARISING FROM THE USE OF THIS PRODUCT THIS WARRANTY GIVES YOU SPECIFIC LEGAL RIGHTS AND YOU MAY ALSO HAVE OTHER RIGHTS WHICH MAY VARY DEPENDING ON WHER
